SPEIFIATION forming palit Of Letters Patent ND. 625,871, d'ed 30, 189.9.Application filed January 27,1898. Serial No.` 668,178. (No model.)`

To all whom, it may concern..-

Be it known that I, JOSEPH BUSHA, a citizen of the United States ofAmerica,` and a resident of Pittsburg, in the county of Allegheny andState of Pennsylvania, have invented certain new and useful Improvementsin Hose- Nozzles, of which the following is a specification.

This invention has particular reference to that class of hose-nozzlesfor flremens use constructed to throw both spray and solid streams; andit consists in certain peculiari-` ties in the construction of theelements and in certain novel combinations of parts, substantially ashereinafter described, and particularly pointedout in the subjoinedclaims.

The main object of the invention is to provide a simple and practicalnozzle capable of throwing a solid stream, a spray, or both a solidstream and spray at once, at the will of the operator. This obj ect andothers hereinafter appearing are accomplished by the constructionillustrated in the accompanying drawings, in which- Figure 1 is a sideview, partly in section, showing the parts in position to throw a sprayFig. 2 is a longitudinal section showing in dotted lines the parts adjusted to throw both a spray and solid stream and in full lines the partsadjusted to throw a solid stream alone. Fig. 3 is a plan view of theforward end of the nozzle with the tube through which the solid streamflows shown in section. Fig. 4 is a detail representation of 'said tubefrom two points of view. Fig. 5 is a detail sectional view of theforward section of the nozzle-shell. Fig. 6 is a rear end view of saidshell-section. Fig. 7 is a detail view of the rear shell-section,looking at the forward end thereof. Figs. 8, 9, and 10 are detail vviewsof parts of the dev1ce.

The same reference characters are used to designate the same parts inthe several views. The shell of the nozzle is composed of three sections1, 2, and 3, threaded together. Within the forward section 1 is a sleeve4, which is connected with the inner wall thereof by ribs 5 and is soarranged within said section as toleave a Water-chamber 6 between thetwo, throughwhich chamber the water to be sprayed flows. Extendingthrough and beyond said sleeve and guided. thereby is alongitudinally-movable tube 7, to the upper end of which is secured thetip 8 and the lower end of which is provided with a circumferentialflange 9, orming a valve which when the tube is in its foremost positionis seated against an offset 10, projecting inward from the intermediatesection 2, and thus closes communication to the chamber 6 and causes allthe Water to flow through the tube 7 and issue from the tip in a solidstream. Extending toward each other across the rear shellsection 3 arearms 11, at the junction of which is a sleeve 12, through which extendsthe stem 13 of a freely-movable valvel/l, which is forced forward awayfrom the forward surface of said sleeve 12 by the pressure of theinflowing water. Said stem has at its rear end a head or enlargement13a, which engages the rear end of said sleeve 12, so as to confine theforward movement of said valve to within certain. predetermined limits.

In the operation of the device when the parts are in the position shownin full lines in Fig. 2 the water will issue from the nozzle in a solidstream only..` If now it is desired to cause the water to issue in botha solid stream and spray, the tube 7 is forced inward a portion only ofits whole extent of longitudinal movement, thus forcing the valve 9*away from its seat 10 and opening the inlet to the water-chamber@ (whichhas a spraying device, hereinafter described, at its forward end)without'closi-ng the inlet to the tube 7, so that the stream ofinflowing water will be divided, one portion iiowing through the chamber6 and the other portion .iiowing through the tube 7. ter to issue inaspray alone, said tube7 is moved rearward its full extent, thusbringing its rear end into engagement with the valve 14, and therebyclosing the inlet to said tube 7.

The means preferred by me for causing the longitudinal movement abovedescribed of the tube 7 consists of pins orribs 15, projecting laterallyfrom the lower end of said tube and received within openingsl, formed atdiametrically opposite sides of the inner end of said sleeve 4, each ofsaid openings having a curved wall formed to provide twosuccessively-arranged cam-surfaces 17 and 18, with When it is desiredtocause the-wa- IOO a depression or seat 19 between the same and withdepressions or seats 2O at each end of the same. The construction issuch, therefore, that when the tube 7 is turned in one direction thecams engaged with the pins thereof will cause it to move rearward andwhen turned in the opposite direction the tube will similarly be causedto move forward. The seats 19 at the j unetions of the two cams of therespective pairs of cams 17 and 18 are so located as to hold the tube 7in its intermediate position when engaged with the ribs or projections15, and they allow said ribs or projections to be freely releasedtherefrom and the tube to be forced forward or rearward of its saidintermediate position when said tube is turned in one or the otherdirection, as the ease may be. v

The spraying device hereinbefore referred to is located at the forwardend of the shellsection 1 and comprises a stationary ring 21, having aninwardly-beveled outer wall.

threaded upon the forward end of the sleeve 1 and preferably lockedthereon by the threaded ring 22. The mouth 23 of the shell-section 1 iscorrespondingly beveled, and the bevels of the ring and mouth arepreferably relatively such as to cause the water to issue from thechamber G in almost a solid stream and spread gradually into awidely-spread spray after it leaves said chamber, thus eliabling thenozzle to be used in spraying through a small opening without wettingthe firemen who are directing the stream.

In Fig. 10 I have shown a spraying-ring21n having a plain beveled wall,which when this construction is used will be at a slight distance fromthe beveled mouth of the shell to provide an outlet-opening between thetwo; but the form of spraying-ring shown detached in Fig. 9 and in placein Figs. 1 and 2 is greatly preferred by me, as with it the objects inView are better attained. In said construction the beveled o uter edgeof the ring 21 is preferably in contact with the beveled mouth of theshell and is serrated to provide alternating V-shaped openings andV-shaped teeth.

`This serrated ring is preferred to the plain V-shaped teeth andopenings cause the water to consolidate at the points of the teeth andissue in an annular jet. It has also been found in practice that thejet-openings in the serrated construction of ring are not so liabletobecome clogged with dirt as is the sprayopening provided by the plainring.

A spring has heretofore been employed in a similar type of nozzle forpreventing accidental longitudinal movement of the tube 7 by the joltingto which the nozzle has been subjected in drawing it from place to placeor when turned upon its rear end. The forward end of this spring,however, was engaged directly with the rear end of said tube and itssaid forward end was of less diameter than its rear end, whereby itsometimes became more or less compressed under the inuence of thepressure of the inflowin g water and also frequently turned on its seatwhile the tube Was being turned. To overcome these disadvantages, thespring 25 in the present structure is of the same diameter at each endand its forward end is set in depressions 26, formed in lugs 27,projecting laterally from a ring 28, (shown in detail in Fig. 8,) whichlatter loosely encircles the rear end of said tube 7. The rear end ofsaid spring is seated on an offset 29 within the shell-section 3.

Owing to the great pressure of Water necessarily used in extinguishingfires and to the fact that the inlet end of the nozzle is ofconsiderably greater diameter-than the tube 7, the water is liable toenter the latter, particularly when the sprayingchamber 6 is closed, ina very wild condition, and unless this is corrected the nozzle will bevery difficult to hold and control. To overcome lthis disadvantage, apartition 30 is placed in the inlet end of the tube 7, which partitionextends across the tube from wall to wall thereof and serves tostraighten the stream within said tube.

The forward end of the tube 7 is preferably provided with a nut 31,threaded thereon for convenience in turning it.

It will be observed that the construction of the shell is such as toafford access to the several inner parts of the nozzle and that saidinner parts are separable and may be removed and replaced at pleasure.It will also be observed that the construction of the nozzle as a wholeis simple, durable, andpractical and that it may easily be adjusted to'throw either a solid stream or a spray, or both a solid. stream andspray, at the will of the operator.

I do not wish to be understood as limiting myself to the precise detailconstruction herein described, as-many of the details may be variedwithout departing from the spirit of the invention; but
